Queensberry was an all-female German pop group, founded in late 2008. Formed during the seventh season of the German version of the international television talent show Popstars, Popstars - Just 4 Girls, the original line-up consisted of singers Leonore Bartsch (Leo), Gabriella De Almeida Rinne (Gabby), Antonella Trapani (Anto), and Victoria Ulbrich (Vici).[1] On 7 July 2010, it was announced that both Antonella and Victoria had left the group, to be replaced by new members, Selina Herrero and Ronja Hilbig.[2]

After numerous elimination rounds, sixteen candidates flew to Sharm El Sheik, Egypt, where they intensified their training in singing, dancing, and fitness.[10] In the end, twelve girls made it into the band house near Munich, of which six started work on the band's debut album.[10] Beforehand, the top eight contestants, as Popstars: Just 4 Girls, released the single I Believe In X-Mas promoted with a music video. Leo, German-Brazilian Gabriella De Almeida Rinne, who originates from Berlin, and Victoria Ulbrich, all managed to make it into the Queensberry line-up prior to the season's live finale in Hilversum, Netherlands, with all of them having won special stage performances,[11] even though Victoria had had to go into hiatus for four weeks due to her mother's sudden death. Fourth member, Swiss-born, German-Italian, Antonella, was not announced until 18 December, when the show was resumed, based on her having sold most of her version of the group's debut album Volume I (which had been released in three different versions, a week prior to the finale, and featuring one finalist each) and her winning a public televoting over fellow campaigners Patricia Ivanauskas and Katharina Kobert (KayKay).[11] Ironically, although each of the Queensberry girls had already performed together with all of their future bandmates (varying from duets to quartets), at some point throughout the season, it had never happened that all four of them made up one working group together. However, a couple of times, three of the future band members were featured in one quartet, but then with either Leo or Antonella not being part of it.

On 6 May 2009, it was announced that the group was working on its second studio album. The track list included their previous summer song-single called Too Young, the second album's first single Hello (Turn Your Radio On) and one song, which was performed live by former Popstars - Just 4 Girls participant Patricia, called Scandalous. The album was released on 6 November 2009, with its promotional single Hello (Turn Your Radio On) released on 23 October 2009. This album was planned to be the band's first US-album.[12] On 18 June 2010, the girls released two new songs as the soundtrack for the Hanni und Nanni movie, while their record contract with Warner Music in Germany was discontinued.

On 7 July 2010, the group announced on its website that Anto and Vici had both departed from the group. [2] Selina Herrero,[13] a German-Spanish singer from Bad Kreuznach in Germany, who first hit the German single charts in 2008 with Don’t Be Shy and You Can’t Stop Me, and Ronja Hilbig, a singer from Hamburg, who had played the role of Nala in the German version of the musical The Lion King and had been a member of Die Lollipops,[2][14] were brought in as new members. The first appearance of the new quartet was scheduled for 15 July 2010 on VIVA Live. The group made plans to shoot a reality show called A Day in the Life of Queensberry to be shown all over the USA. In October 2010, the group recorded its earlier single I Can't Stop Feeling in Spanish as Yo No Puedo Vivir Sin Ti. The song, written by Teemu Brunila and Kid Crazy, and adapted for Spanish by José Valdes, was first performed on VIVA Live. On 3 December 2010, Queensberry announced it would make a label change and release an album in 2011. During spring and summer of 2011, the group performed throughout Germany on their Pink Chocolate Tour.[15]

The girls guest star on the album of German rapper KittyKat, and featured on a single called No Time For Suckers In April 2012 it was announced that Selina Herrero left the band and went back to school. The remaining members released their third album, Chapter 3, as a trio on 22 June 2012. The first single of the album, Timeless, was released on 1 June 2012. Both album and single charted very low in the German Charts at 90 and 91 respectively. Despite failing at repeating their former successes, a music video for the second single Girl Like You was shot. The single was released on 31 August 2012 and became the first single of the group that failed to chart within the German Top 100.

In August 2012, band member Leo had to drop out from several scheduled concerts of the band due to health issues. Therefore, De Almeida Rinne and Hilbig did several shows as a duo. In October 2012, Leo announced on her official website, that she has left the band.[16] The remaining two members then decided to put future plans for the band on hold to focus on solo projects. In summer 2013, however, it came into the open that they had decided not to perform any longer together.
